In today's laboratories, porcelain-fused-to-metal (PFM) restorations are still among the most profitable restorations — so consistency and high-quality castings are a must.
Technological innovations in casting machines such as vacuum/air pressure casting are helping crown and bridge departments achieve problem-free, high-density castings. High-density castings are the result of passive alloy flow and continuous pressure forcing the molten alloy into the mould as it cools and shrinks. As a result, the castings are more dense and consistent then other casting methods. Notice the grain structure comparison (right). Other advancements such as split crucibles, automatic temperature measuring systems, and oxide reducing vacuum melting cycles help eliminate the costly errors of miss-casts. If you're considering the purchase of a new casting machine, or would like to learn more about vacuum/air pressure casting, please contact BEGO USA. + Download Nautiluss CC Plus brochure |
